For the first time in human history, a volcanic hyper eruption blows through the surface of the Earth. A bad day for Planet Earth as the disastrous results threatens the very future of mankind.
Something weird seems to be happening to our weather - it appears to be getting more extreme. In the past few years we have shivered through two record-breaking cold winters and parts of the country have experienced intense droughts and torrential floods. It is a pattern that appears to be playing out across the globe. Hurricane chasers are recording bigger storms and in Texas, record-breaking rain has been followed by record-breaking drought. Horizon follows the scientists who are trying to understand what's been happening to our weather and investigates if these extremes are a taste of what is to come.
Volcanologist Tom Pfeiffer and his team are embarking on their most daring adventure yet--visiting and photographing two remote Indonesian volcanoes, among the 20 most active in the world. Join a tense journey into the heart of one of nature's most dramatic and unpredictable natural phenomena, one that will test this experienced crew of scientists and native guides.
